In The Ocean

Subnautica 2 Prologue — **Interacting With The NoA.**

After creating a character of your choice, press Tab to check your PDA. In the adaptations section, you will find all the information about the character’s status. Interact with NoA, the ball, then boot and download its image to open the Adaptation Chamber’s door.

Move ahead and enter the Biolock Room to get examined by the computer. However, it’ll determine that your health isn’t suitable for exploring the outside world. So, exit the room and turn left to the Sampling Pavilion. Interact with the Angel Comb there, and return to the Biolock room to complete the test.

The door to the lifepod will open. Activate the switch to your right, and then drop into the ocean. Swim upwards to the chamber ahead to save the game.

Turn around to find another NoA, and then assess it to launch a mission. Unfortunately, the lifepod’s locks are corroded shut.

Now, leave the lifepod and go around it to find two locks, then open them. Return to NoA and activate the mission to finally leave the ocean dramatically.

On The Land

Once outside the ocean, use the Storage Box in the lifepod to find one medkit and three nutrition bars. With this, exit the lifepod and head northeast. After crossing a wasted machine in the ocean, look at 340 to find another Pink Flower Bulb, similar to the one in the Sampling Pavilion; these are called Angel Comb.

Interact with it to unlock an adaptation ability that allows you to eat Alien Food, and look down to find Anita’s black box. Return to the lifepod, and go southeast underwater to find the Welcome Center; that’s your first destination.

Welcome Center

Swim inside the Welcome Center, and to power it up, you will need a Battery. First, pick up the Metal Salvage from the ground to open a path to an underwater cave, and there you will find an Oxygen Tunic, a plant that emits oxygen bubbles. Get into the bubbles to refill your oxygen.

Next, search around the cave to find Copper and Titanium. You need two Copper and one Acidic Raion Pouch to craft the Battery. First, use the Titanium you’ve discovered under the Welcome Center to craft a Survival Multitool to salvage the Acidic Raion Pouch.

See a brain-like plant with a medical gel sac in the middle? That’s the plant you’re looking for. Use the Survival Multitool to cut its pouch to salvage it.

Copper can be found in underwater caves, and the crashed ship to the northwest of your lifepod. Don’t worry about the oxygen supply, as there are numerous Oxygen Tunics inside the caves. Use their bubbles, collect the Copper, and return to the life pod.

**Using The Fabricator To Craft A Survival Multitool.**

Use the fabricator to create a Basic Battery, and go inside the Welcome Center to power it up. With this, the Welcome Center will become active, then interact with the NoA to retrieve information about it. It also reveals the planet’s name: Proteus.

Additionally, you will need a Scanner from here to scan everything and find blueprints to craft items. Here is everything that you need to craft a Scanner:

2 Quartz
2 Titanium
1 Basic Battery

Colonist Bunker

Now, you have to find Chap’s black box. Head southeast from your lifepod to find several rocky pillars. A giant crab will wake up after a Hammerhead interacts with it; don’t worry about it. Go deep inside the cave below the rocky pillars to find an active base called the Colonist Bunker. Inside, you will find Chap’s black box.

After picking it up, turn left to find a Biobed. Interact with it to expand your inventory by one slot. Before returning to the lifepod, salvage any material you see in the cave. If your inventory is full, use the storage box in the lifepod to make space.

Camp One

With the information you have retrieved from the Colonist Bunker, it’s time to head towards the next location: Camp One. Camp One is located 250 meters northwest of the lifepod, which is a channel of numerous broken tunnels.

Get there, and avoid the massive fish called Marrowbreach. Hide in the tunnels to avoid it, and head into the main chamber of Camp One to find further information about the colonists of Proteus. Scan all the items, which include a Flashlight, Tree Painting, and Wakemaker Fragment.

**Entrance To Camp One’s Main Chamber.**

The main section of this area is separated by the Marrowbreach, and to get inside it, go under the rocks and find the tunnel leading to the main chamber.

With the datapad from Camp One, you will find out about the next location to explore: The Old Habitat.

The Old Habitat

420 meters northwest of the lifepod exists the Old Habitat, another abandoned base of the Colonists. Follow the Quaker’s black box marker to find the Old Habitat’s exact location. To enter it, get to the bottom and use the hatch.

If you’re low on oxygen, use the oxygen tank’s bubbles flowing upwards; swim into them. Swim to the base’s top to find NoA, then boot it to learn about The Old Habitat. Now, collect Quaker’s black box, then follow it up with Dr. Wu’s black box to complete this area.

From here, we need to get Wander’s black box.

Wander’s Black Box

Return to the lifepod and move southwest to find Wander’s black box. There, follow the current to enter the tavern; make sure to craft the Sonic Resonator and destroy all the webs, Bloom Cankers, to create the path forward.

Beware of the giant claw in the tavern, as it deals significant damage. You can’t destroy it with the Sonic Resonator. So, avoid the claw and pick up Wander’s black box, then break all the Bloom Cankers to free the claw. Now, follow the northern tendril to find an Angel Comb, which consists of a plant that gives you another Adaptation.

However, don’t interact with it yet. Follow the tendril, and break the Bloom Cankers at its end. Return to the Angel Comb and destroy the remaining Bloom Cankers to open it. This will provide you with Heat Tolerance Adaptation, allowing you to travel further into the ocean.
